VICE rr-net behavior in WARP mode?

I am seeing behavior that indicates that IP65 DHCP does not function reliably when VICE is in WARP mode. It seems to be a timing issue that is a function of VICE not emulating the receive buffer in the CS8900a. This is outside of my domain so I could easily be wrong and I thought I might find a sanity check here. I am trying to write an application that will use networking and I would like it to run in WARP mode reliably as it does some very heavy math for encryption functions and it is _SLOW_ in real time. I also kind of thought that if it all worked in VICE in WARP my odds would be better in turbo mode on the U64 20Mhz  or C64U 64Mhz modes.

Thanks,

Justin
