maybe you want to contact jens schönfeld (jens_at_ami.ga) and tell him you need 
hardware to create/test/support/whatnot rr/silversurfer/rr-net drivers... 
with some luck you might get stuff sponsored (i did :o))

actually the use of NMI for this is more or less a "tradition".... also most 
software that uses the swithlink (or any other serial cart for that matter) 
uses NMI. i think there are other reasons aswell... the latency involved in a 
"normal" IRQ vs NMI (routed over $0314 etc vectors) may make a difference.
