Most UDP should not hit the MTU limitation.
The common ones that come to mind are streaming audio/video and DNS.

Subject: Re: [c-nsp] ip tcp adjust-mss

For UDP, one would have to do something like touch the end-hosts and adjust mtu 
size on the ip_stack itself.  Not very scalable and may require too much 
touch-points (also would be somewhat permanent).

Some client vpn shims do this to end-hosts after installations of said software.
