Thanks for the responses everyone. I'm thinking I will wait to look into this further, as I do already have a lot on my landscaping plate at the current moment, let alone trying to get into grafting. Nate, is it something you think should be easy for a newbie, or does grafting take a bit more learned skill and tools/materials do you think?
foxd, you sent me a couple of your extra seeds, and I had the same result. I think it is the lack of cold stratification on my part, not sure if you used it on your seeds? I'm keeping them in the container though just to see if they do come up at some point!
cuttlefish, you're right about my mis-terminology. Still learning the horticultural terms, heh.
BTW, most of the sites that talk about germinating seeds talk about needing at least 3 months of cold stratification, or they don't come up very well if at all. This page explains a little bit, and most sites have mentioned putting the seeds in damp peat or perlite in a ziploc bag, then storing in the fridge for months. This site says it can be over a year, but it also has some good explanation on why how the japanese maple seed. They say also not to throw them out if they don't germinate, as sometimes they germinate after the 2nd wintering.

The other thing I see mentioned on the sites is that it is imperative that it is FRESH seed, otherwise it becomes less viable quickly. This is something I have noticed with the 3 types of bamboo seed I have tried germinating. All germinated almost 75-90% when I first got the seed. 9 months later, almost NONE of the seeds are coming up, and I have kept them in an airtight container in the fridge.
Too bad I don't have a cheap source for japanese maple seeds. Cuttlefish if you go back to your nursery this fall, keep me in mind, heh!
