If you share libraries on a network does that also allow you to share/see the apps in the other libraries just like the songs?

It does not for iPhone apps, so I'd guess it does not for iPad apps either.

My ITunes home network sharing shares all my iphone apps across 4 computers and then to use on all three family phones. I assume as they are both in itunes, IPad apps will also.

I think that all shares must be on the same iTunes account to work.

I am thinking the computer must be authorized to an account, not necessary to be the using same account. My daughter has her own itunes acct, but her macbook is authorized to my stuff, so she can use my apps.

I share my iphone apps already so I'm sure it's the same for ipad apps.

Hmmm... I'll have to take another look at my wife's macbook. I didn't think that apps showed up when using home sharing. I could very easily be wrong about that, though.

Look hard as they are mixed in with everything else. on your computer, open up her library in itunes, click the down arrow to see what is in it and there should be a apps icon. I that doesn't work check your sharing settings.

From iTunes Help:

"You can share movies; radio station links; and MP3, Apple Lossless, AIFF, WAV, and AAC files. You can’t share programs purchased from Audible.com or QuickTime sound files."

No mention of Apps. However if you are all on the same iTunes account or authorized on each others machines, nothing is stopping you from sharing apps as I understand it.

I just checked my computers, all the ipad apps I purchased today are now on all computers including my media server and my daughter's MacBook Air who has her own itunes acct. They are all authorized for my itunes account.
