Yes, I was about to suggest any remote meeting/conference software as an alternative. You usually have the possibility to share and often control remote desktop. Or - here is the blog describing running OpenVPN over UDP tunnel setup using SIP servers. Note that connection itself is still peer-to-peer - an external server is used only to announce external addresses. This may or may not work depending on exact infrastructure (the author had to work around double NAT) but the idea is interesting and somewhat in line with using Jabber (which effectively does the same UDP tunneling). This is in Russian only, sorry. https://habr.com/ru/post/482888/
