I don't want it to simply appear on somebodies device as that would be a pretty serious security problem. I am thinking more along the lines of making it available to view/download.
The whole point of what I am asking is because I want to be able to share a pdf to several people without having to know their email addresses, dropbox accounts or have them have to look on a particular website. The idea is that I want to provide something for people to be able to download instead of having to give them paper.
It is not unlike when you go to a play or concert or something and they give you a piece of paper or book or something that gives you details about the people or about what they are doing. (This is not what I am doing exactly, but it is essentially the same) I want to be able to provide that resource to these people for download on whatever device they brought with them (probably their phones or tablets).
As I said initially, I am aware of several apps and different things that can do it, but I want to know if anyone has read about/encountered/used something that can do similar to what I am talking about. Broadcasting a file (or however you want to say it) so that people can choose to view/download the file if they would like.
Thanks for the explanation.
Are you trying to distribute this
only to people with whom you have face-to-face contact? In that case, it's similar to handing out a theater playbill. A technology like
AirDrop in iOS/OS X will work - you have the document open on your device, you press Share, people nearby who also have an iOS device/Mac
and have AirDrop activated will be asked if they want that document. Android also has the equivalent, but the two platforms don't speak to each other - there is no universal solution.
If you do not have face-to-face contact, I think there's a fundamental flaw to equating this with handing out a theater playbill. How do you put the playbill into their hands if they are not present at the theater? The answers are much the same whether the document is a sheet of paper or a digital file - mail/email, post it on a bulletin board/post it on a web page, tell people how to obtain a copy, tweet the link to your followers, post it on your FaceBook page, get mentioned in the press....
Could you explain why you
don't want them to "look on a particular web site," yet
do want to give them a download link? If you mean that you don't want to leave discovery to chance (by posting a web page and doing nothing afterwards to promote it), that's understandable - you'd rather push it into their hands in some form. But from a technological standpoint, whether a link triggers a download or opens a web page is a very narrow distinction.
Bottom line, if you want to reach 100 strangers, you need a method that all or nearly all will be able to use, with a minimum of bother. There are only two nearly universal methods of doing this on smartphones, tablets, and laptops - email, and web page. And even then, people have preferences. "Send me email and I'll reply with a link. If you'd rather not share your email address, go to my web page."
