in front of the class

tonight in my operating systems class we were talking about some material
which was relevant to Isilon, so Hank (the prof) asked me before class if
i would be willing to come up for a bit and talk about it. he wasn't sure,
but in the middle he did invite me up and i spent about 10 minute talking.
i wasn't real prepared so my "presentation" was poor (non-existent, really)
but i did answer some questions. it was exciting. i've been in touch with
him a bit more about research and it is looking more promising with each
communication.
