No, it's not that.

If I understood your post correctly, you're asking if one could 
implement OpenVPN without a TCP/IP stack, though you supposedly have UDP 
support already (written directly at application level, or do you have 
an IP stack but no TCP?) on some unspecified embedded OS with an 
unspecified level of POSIX compliance on which a tun/tap adapter may or 
may not be available.

In any event, it's pretty unclear what you're asking. It's also unclear 
how much effort you're willing to put into it. OpenVPN is intended to 
work in a POSIX environment with OpenSSL, a conventional BSD sockets 
style IP stack and a tun/tap adapter available. Can you get it to work 
elsewhere? Sure, with enough man-hours... but the number of hours 
involved may be prohibitive, and you may have ended up rewriting not 
just OpenVPN itself but its dependencies as well by the time you're through.

So -- you asked a big wide-open problem (read: "time sink") without a 
simple, clear answer; you contradicted yourself in parts; you used a 
subject line which had *nothing at all* to do with the content of your 
message; and you left out pertinent details. Is it a surprise you didn't 
get a response?
