If I use blocked views, does each sub block constitute a separate file?
It doesn't look like you can control the number of blocks, so will
Metakit automatically split a large view into enough blocks that each
is less than 2GB.
I had thought of using two integer columns to represent a decimal. By
adaptive, do you mean Metakit handles arbitrarily large integers? That
would be awesome if it did.
I can live without unicode for now, but I hope there's plans to include
it in the future. BSDDB doesn't really support unicode either. Does the
C interface support it?

1) On 32 bit systems, the file size limit is 2GB. It is more on
64bit. If you are using large tables, use blocked tables otherwise
you will die a slow horrible death. If you have indexed keys use
blocked, ordered tables.
_vw = st.getas("blocked[_B[id:I,data:S]]")
st = _vw.blocked()#.ordered() if an ordered table
2) decimal types
No, metakit doesn't have support for decimal types, I have had some
sucess using two integer columns though to represent decimal numbers.
Sorting requires a sort on two columns for instance.
Since metakit's integers are adaptive, this doesn't take up any extra
space.
The python interface at least doesn't support unicode verty well.
Hope this helps.
