I stick to jEdit, but didn't bother yet to integrate something like syntax check or remote execution.

I installed the subversion plugin which gives me, in combination with the Project Viewer plugin a great way of handling my working copies.

When I need to edit something on remote hosts, I use the (s)ftp plugin. It downloads a copy of my remote file and uploads then when I save them.

There is also an ssh shell plugin but I couldn't yet get that to work.
