In reply to jsmcfarland:
A boulder route is something that is part boulder problem and part roped climb.
Some long boulder problems (like traverses) get given route grades and I think that makes a lot of sense in describing the difficulty. However using the same grading system doesn't make them routes. They are still boulder problems. They protected by mats, can be practiced alone usually, and are more accessible. Routes are climbed with a rope and that makes a significant difference.
The hybrids that are now being created are a fairly new phenomenon and a mixture of the two and I think it makes sense to recognize that.
