Socat possible / sensefull?

Hello Community!

Iam using openvpn on my vserver for my mobile phone and netbook when iam in "public".
Now i have a friend who is behind a firewall where only port 443 ist allowed to "ssl;tcp out".
But my openvpn ist listening on UDP port 4711.
The Question is if it possible to forward tcp to udp using socat or something like that?

Cause when i change conection method of the openvpn to tcp:443 it limits the speed of the tunnel to ~10mbits.
As while i have ~100mbits using openvpn on udp:4711.
Multiple instances of openvpn is the last choice, cause of low serverside resources.

Does it make any sense using socat? Will it work?
Or is there a way to improve speed/performance using tcp?
How could this be done?

Thanks for your time!

I've tried this once and never got it to work: there's a slight protocol difference between the UDP and TCP encapsulation, which makes it impossible to do this.
