Well, nothing stopping you from treating your datagram-based VPN (ie, DTLS) as
an IP tunnel, and doing TCP-like stuff on top of it to handle the IM and file
transfer. Actually I'm working on something rather like that now, which may or
not get finished soon.
*lol* aren't we all.

you can do SSL over UDP if you like - I think most VPN software is UDP
only, while OpenVPN has a fallback TCP mode for cases where you can't
use UDP (and TBH there aren't many)
I've never used
