These two questions were fairly open-ended so responses varied greatly. I
will summarize the responses that I found most helpful.

My vendor was incorrect, I can obtain processor upgrades for the SS10. I
have the option of either going to 2 or 4 processors from at least two
different manufacturers. Most people felt that going through Sun to obtain
the Texas Instruments chips was too costly, although this is an option. The
recommendation that came from multiple sources was to contact Ross
Technologies in Texas (800-774-7677) to obtain their 90 MHz HyperSparc
processors. The 90 MHz clock speed cannot be used as a direct comparison to
the 60 MHz TI chips. Most people felt that the Ross 90's and TI 60's gave
similar performance. Ross' price for 4 chips was 14K.

About recommending a machine for upgrading 1, 2, 3 or 4 years in the future.
 Most people felt that it was not wise to purchase a machine that cannot be
maxed out in 12-18 months. The reason for this is that technology will be
so far ahead in that time you will want to buy it. Most responses talked of
64-bit processing from Sun in the 12-18 month time frame.

Thanks to all the replied!
