Hi David,

That would be terrific!  We're primarily looking for:

- VMS with multiple focal planes
- NDPI with multiple focal planes
- VMU samples (we don't have any!)
- (any other Hamamatsu flavors?)

and secondarily:

- Ordinary VMS scans (in case the format has changed in the last few years)
- Scans at 20x (most of our samples are 40x)

If you can *also* give us permission to publicly distribute the scans in 
the openslide-testdata dataset, that would be *incredibly* helpful: our 
automated test cases can only use the redistributable data.  We would 
need a signed letter from the person responsible for the slides.  (The 
content of the scans is not very important, so feel free to use 
low-value slides.)  If you might be able to arrange this, please contact 
me off-list and I'll send you the form letter.

Thanks!
