Yes, as long as your iTunes/App store account is not over it's authorized limits you can install on all three. See Talmy's post above.

No limits at all. The iTunes 5 system limitation is a separate limitation that doesn't apply to Mac App Store apps.
So you're telling me that; the 36 iMac's we have in our lab here could use one license of Lion to install on everything??
If our boss who "owns" them purchases it, then installs it on all "her" computers....
please tell me this is true.
