I have a HDTV capture card (USB actually) and I'm wondering if I can record directly to a USB flash drive (just saw a 8GB SDHC CLASS 6 on sale).
In this way I can transport it w/o having to transfer files from HDD to portable media.

Is the flash drive fast enough for this?

As long as flash drive is USB 2.0 and so are your USB ports it should work.

I would think the flash drive wouldn't be nearly fast enough, epecially once the interface starts bogging down. Flash drives are way slow compared to hard drives. Even laptop drives blow them away in speed.

So re: whether it'll be fast enough: 1 yes vote and 1 no vote.
Does anyone have a USB flash drive that they can use to test it?

I'd be surprised if you couldn't; yes, flash isn't as fast as DRAM, but I'd say it would most likely compare favorably write-speed wise to magnetic disk (what with the lack of moving parts and all). Also, keep in mind that ATSC's peak bitrate is about 19.2 Mbps; that's just shy of 2.5 MB/second. A fair amount, but for modern systems, not that bad; as mentioned above, as long as (a) the port and USB flash device both do USB 2.0 (and any intervening hubs, if any), and (b) you have enough capacity, it should "just work"...

I just did a quick test transferring a large file (iso CD image) to my flash drive.

Average transfer rate 7.6 Megabytes per second.

Using a Lexar Sport USB 2.0 flash drive, and USB 2.0 ports on my PC.
