[CQ-Contest] Is there any HTTP cluster streams (not telnet)?

[Sterling Mann]

In a nutshell, I'm on a network that blocks non-standard ports including
telnet, making it a pain to use DX cluster since I can only access web
clients like DXsummit.fi. Before I go down the route of begging for
telnet/non standard port access, is anyone aware of any development of HTTP
cluster streams? Or maybe a telnet cluster on port 80?

I lack networking expertise so go easy on me.

Thanks,
