You should estimate the size of each object and add them up. Remember that 
a new version of the object is stored each time it is modified and commited 
(packing the database removes old versions). You can use pickle to estimate 
sizes.
That is, for the objects that users can create; dtml's, page templates, 
scripts etc. that you have already created make the current 10MB of Data.fs

No, you can have many more simultaneous users. Don't worry about this. If 
you really have a high-load site you could play with this setting and 
pool_size (search the list archives for more info).

LFS = Large File Support
Python 2.2 includes this automatically if the platform supports it. For 
Python 2.1 it must be enabled explicitely. To check if it works for you, 
locate and execute test_largefile.py

Unless you expect things to explode, I would not worry about it reaching 2GB.

Did your Data.fs file really grew up to 2GB? Being currently at 10MB?
Maybe it's another file related to your application. Or you need to pack 
more often...
