Rabbit, Netburner, or ?

I have an application that will write UP TO
2k bytes of data per day (often, less) for
seven days a week into a battery-backed RAM
chip. The data each day would start at a 2k
boundary and unused bytes from the day before
would be zeroed. I want to present the data
via HTML as form data to a web browser as long
as the data is non-zero. When a zero is
encountered, the web processor should skip to
the next 2k boundary and start sending form data
again. The web processor needs to access the RAM
chip only when sending the form data to the web
browser; the rest of the time, the application
processor will have priority over the address
lines.
Is there a network-enabled processor that can
conditionally send HTML code by addressing data
in an external RAM chip (off-chip address and
data buses) while monitoring a DISENABLE port
pin for permission to address the chip?
I am not prepared to write an OS or TCP/IP stack
application from scratch. I like the RABBIT's
ease of programming, but I need a 14 bit external
address bus plus extra handshake pins.
Can I add anything to make my question clearer?
Any suggestions would be appreciated.
TIA
Rick
