James is the person to speak on whether he'd consider the feature. Just
looking at it from my perspective...

Hmm. There's a definite latency penalty involved in doing that. Could you
use IAX2 trunking? It's built with your individual application in mind,
and consequently might be somewhat more effective.

Likewise, you could probably have another userspace bridging tool that
does that (reads packets from the "real" interface, does
packet-aggregation as appropriate, writes them to the tun device that
OpenVPN is listening on), rather than needing this to be implemented in
OpenVPN itself. It would still be a useful feature for folks who *aren't*
using OpenVPN, right?
