What does "limited" mean?  Tahoe doesn't actually require all that much, by 
modern standards.  Large files are processed in segments.  I have a Linux 
Virtual Server which I'm using as a helper node, and it only has 512 MiB 
total (hard limit, no swap), over half of which is being used by other stuff.  
Hasn't been an issue.  When I asked if it would be, Brian (IIRC) said that 
Tahoe's working set size is around 40 MiB.
