I am not sure why you want to have a BigTable PageStore since it would
have quite negative performance implications (imho). you may consider
also the presentation of Guido van Rossum
https://sites.google.com/site/appengineappstats/AppStats_Meetup09.pdf?attredirects=0
I attach an implementation of a Memcache-based PageStore to this mail.
It is very much based on the code posted by Richard Wilkinson some time
before. If you find any bugs or are able to improve it, please post it
to the list.
regards,

I need to write app specifically for GAE, I know Disk based page store
wouldnt work. Is there any existing solution for this? I searched mailing
lists and did googling, seems that it has been discussed earlier too, but
I don't find any implementation.
If I can get a prebuilt solution, I want to avoid my self from writing.
