I'm not yet through with it, and promise I'll try to deliver more useful
comments soon. But here's the first thing which kinda bewilders me:

A loopback sends packets back to the originator. Hence the name. You
propose point-to-point links. A bunch of virtual crossover cables,
similar to the original association between backends and frontends. So
naming it 'XenLoop' is kinda misleading.

kind regards,
daniel

PS: I hereby admit that XenCross sounds plain stupid. :)
