> I would really like to standardize on AES-GCM going forward for new protocols. But right now I can't use that in Windows .NET without writing my own AES code. Hmmm.

See http://blogs.msdn.com/b/shawnfa/archive/2009/03/17/authenticated-symmetric-encryption-in-net.aspx for an example using the authenticated encryption support in .NET.  Substitute CngChainingMode.Gcm for CngChainingMode.Ccm in the code and you're off to the races using GCM in .NET.
