Are you serious when you are talking about 8-man tablebases? Please notice that 8-man tablebase will be ~60 times larger, than 7-man tablebase, 7-man tablebase will be ~60 times larger, than 6-man tablebase, and 6-man tablebase is ~60 times larger, than 5-man tablebase. So, average 8-man tablebase would be ~60*60*60 = 216,000 times larger, than average 5-man tablebase. Assuming size of average 5-man TB equal to 100Mb, we'll have size of 8-man TB equal to 20,000Gb (all calculations are very approximate, of course). And please notice that there are much more different 8-man TBs than different 5-man TBs. So it looks that for now practical limit is 6-man TBs, if you can spend tens of gigabytes (hundreds, when we'll have more) for them. You can get statistics from Crafty site, look at TBS files in TB/tbs directory.
