If anyone is interested I've exposed the google c# api to lotusscript, and have been working on a sync myself.
I've got lotusscript reading and writing the google calendar, but, I have not had time to actually make it sync.
I can be contacted directly at:
dwight@dwightwilbanks.org
msn:dwight_wilbanks@hotmail.com
yahoo:dwight_wilbanks@yahoo.com
aim:dwightwlbnks
gtalk:dwight.wilbanks@gmail.com
Since my schedule does not permit, I would like to hand off what I have already done.
