[Zope] CoreSessionTracking and noundo db

hi in trying out the excellent CoreSessionTracking product, i encountered a little problem. the doc reference a no-undo external db to house the data. i remember one such beast which were alpha (berkerly dbm(?)), but can't locate it at zope.org. also, will there ever be a no undo db for use with zope? since such product is a must to run zope in real world. hints, urls welcome thanks -- http://www.kedai.com.my/kk http://www.kedai.com.my/eZine Strange how laughter looks like crying with no sound, and raindrops taste like tears .. without the pain
