and least we lose sight in the frenzie here-)) http://www.kitely.com/ shows one can get up to 16 regions, even in mega mode [no region border crossing issues] for 100 USD...only 25 more than for one very limited rental of a region in inwz....
a no brainer to my thinking-))
[this is not a response to you Ilan but to the inwz posters and lurkers that are obviously around--tho I knew they would be]
Hopefully Jim will continue to pass on further commenting as he at least once did in another blog about how mega regions, which Kitely and many in opensim use very well, as a "kludge".
