#71 looks interesting, but I think it's gotta have the name. I'm also concerned about the kind of web 2.0 shine aspect that makes it look glassy. How will that come across on a shirt or a pint glass? # 68 is also great, but one thing that makes it cool is having the words in the lower left corner - if you put this on a shirt or a pint glass, you'll just have the words on a solid or clear background, and the placement will be lost.
you can take the gloss off for the glass because the glass with give you a gloss. we can put a box around it to keep it in the bottom corner. there are many options for this logo. let me know if you need anything else.
