What limitations?  Or, put another way, how severe are these
limitations?

I suppose it's unlikely to become a practical problem right now, but
you'll have to deal with it sooner or later, if this multiple
connection thingie catches on...

Frog knows.  Maybe you could tag the packets with connection number.

Well, any (that is, most ;-) tiles have got exactly eight neighbours.
Thus, assuming that all goto routes are from adjacent tile to adjacent
tile, you could pack each step into only 3 bits, which is a lot
shorter than two shorts (32 bits?)  I suppose that might be good for
traffic anyway, but it might not be worth it if it takes a long time
to pack / unpack.
