One of the first things to explore is if its possible to dispatch
different isodep applications to different apps. I know you can add an
intent filter matching action=3Dandroid.nfc.action.TECH_DISCOVERED and a custom "tech filter" android.nfc.tech.IsoDep. However, as long as= there
is no mime type or similar concept, apps will always fight for access to IsoDep endpoints. We will want to avoid that situation.

Subversion Kills Productivity. Get off Subversion & Make the Move to Pe= rforce.
With Perforce, you get hassle-free workflows. Merge that actually works. Faster operations. Version large binaries. =C2=A0Built-in WAN optimization = and the
freedom to use Git, Perforce or both. Make the move to Perforce.
