Anti-Splog, WP-Hashcash and WPTouch compatibility

Hi,
I'm trying to use WP-Hashcash for splogs, spam and pingbacks. Does the Anti Splog plugin replace or compliment Hashcash?

Could I use the Anti Splog API Key instead of Akismet in Hashcash?

I edited WPTouch to work with Hashcash. (http://thesalmonfarm.org/blog/p/1816) Will I need edits for the Anti-Splog?

I'm running WPMU 2.9.1.1 with Multi-DB.

Thanks,
ChuckS
