Hey - someone needs to post a serious reply in here! (sorry about the threadcrapping - too many martinis)
I've never fit a spider chip, but my general guidelines for clearing a via of soldermask is to take a razorblade and use the corner to scratch away the solder mask.
I find it takes a bit of practice to get use to clearing the soldermask, but you have to sweep left and right while scratching up and down, so that you make a 'waveform' pattern across the via. No need to be gentle, iether. I'm pretty rough with those little bastards (obviosly only to an extent - they WILL tear off eventually. I just scrape until thier shiny).
Patten across via looks like this (but more condensed and more cycles): /----------\ | /\ / | |/ \ / | | \/ | \----------/
Let me know if you need any professional ascii art done. I clearly kick ass.

Yeah but scraping the top clear of soldermask so you have a shinny via to solder too is one thing but the spiderchip has legs which are bare non coated wire that fit inside the via and sometimes the soldermask has gone inside the hole !
People need a sure way method of clearing these holes. Something like grab a pair of needle nose's and grab one single pin from a headerpin and force it into the via and turn it around several times and then pull it out !
