Our training department is promoting numerous interactive video tutorials which are in SWF format. Could it be common to utilize a different devoted host for big amounts of SWFs (like is frequently completed with Video) or are SWFs usually light enough weight that they'll be located on a single platform because the primary site without leading to an excessive amount of additional effect on things?

Please pardon my lack of knowledge here... thanks!

I'd think the greatest impact you are likely to see in your servers (apart from disk space needed for storage from the SWF files) may be the bandwidth consumed as people download these videos out of your servers.
