Drupal 7.x

I am looking porting Drupal to work with Oracle. Is there any interest out there for this?

I'm new to the forum, and semi-new to drupal, so I'm not sure if I posted this in the right spot. If not, let me know.

I was wondering if there was any type of module where a client could upload a video, and place commercials somewhere in the duration of the video, as well as before/after the video plays. The commercials would not be able to be skipped, and be of the client's choosing. I'm thinking something similar to how commercial playback works on hulu. If anyone has any information that could help me with this, it'd be greatly appreciated.

We will be migrating our website to Drupal 7 in the next year. One section of the site, that I am responsible for, is a policy manual. Currently, it is a single HTML page with anchors at each major section.

Are there some good modules that can let me further customize drupal's registration?

For example ajaxify the registration fields and override how drupal responds when an already registered email is entered at registration.

Or other modules that you use and found generally useful for registration

I've started toying with D7. The new interface is hands-down better than D6.
It's been a breeze to set up, and even easier to set up a zen sub-theme.

However, I'm noticing one quirk that I can't seem to nail down.
I've made blockquotes within #content use rounded corners.
I've incorporated border-radius.htc remedy for IE, but have so far been unsuccessful in making it work within the D7 Zen Subtheme.

Just wondering when people think drupal 7 will be a better option to use than drupal 6. Drupal 7 core might be great and all on launch but with so many modules going to be missing it will not really be an option ahead of drupal 6 for anything more than simple sites. So when do you think drupal 7 will pass drupal 6 as the preferred version, a year? Two years? More?
