This list is full of FIXME's, I'm not sure if anybody's working actively on those. I was going to implement a table of capabilities/etc. but then I saw that several fabs have all sorts of special case mentions. Perhaps a subset could be used; the user can always go straight to the fab's website/page to find out the nitty-gritty. Question is, though, what subset should be included?

A specifically difficult metric is pricing comparison. Two layers vs 4 layers vs 6 layers vs 8 layers etc. makes for a quickly-expanding table of hell. Perhaps 3 typical cases could be suggested next to a 'square inch' which seem ubiquitous, and each calculated at each fab, as an indicator only. For limited cases, a fab could be listed on more than one row (e.g. BatchPCB's 2 layer vs 4 layer differences).

Below is an example/test table to play with.

Fab Layers Traces Annulars Spacing Clearance Drill Vias Mask Silkscreen
BatchPCB 2-layer 2 8 - 8 X 20-500 Y red? -
BatchPCB 4-layer 4 6 - 6 X 13-500 Y red? -
DorkbotPDX 4 6 7 6 15 13-260 Y purple ~200
Pad2Pad (low cost) 2 8 - - - 20- Y green ~167

Transposing the rows/columns may be a better layout choice, though that will most definitely cause horizontal scrolling, and is a lot more difficult to edit. And apparently there's no method to sort the columns by a given row. Darn :)
