- How about using some flavor of GEOS VLIR (variable-length indexed record) file
- structure? Plain old random files might work, too; it sounds like you might be
- doing something like this already (the bit about using extra sectors).

- I would venture that the hardware dependencies are caused by doing BAM lookups
- to find free sectors. Assuming the manual is correct (!) a way to get around
- hardware dependencies would be to use BLOCK-ALLOCATE to find your free sectors,
- supposedly if the requested block isn't available, an available block will be
- returned on the error channel. I have no idea if it really works.

- Enough rambling!!
