Although there's been an intervening period of time (close to a year) on this paver sealing treatment posting - I can report some inroads (that could be interpreted as progress . . .). Following the guidance here, I checked at Lowe's and they had something that was exactly what the doctor ordered.
The upsides about this product is that it's water-based, and can be applied with a pressurized-sprayer. The pavers (or other brick) will probably require the sprayed-on material to be brushed a little (to ensure the continuity of the coverage). The other upsides to this product is that product does seep into the material, does give the paver a wet look, is waterproof, and the surface is not left "ice rink" slippery. The one downside is that to really get the desired "wet look" - does probably require that two coats of the product be applied, and the product can be a little pricey. Your best bet is to assume that you'll need more product than you probably estimate you will. Consequently, you'll want to think about buying in the multi-gallon quantity (which is available).
