- Well put Carl.. Don't let the naysayers get to you. Perhaps setting some
- dates might take some heat off of you...

- <br>> Sigh. You people are making *lots* of assumptions. As I said in my
- <br>> first message today:
- <br>>
- <br>> We have no problem scaling back ttl to 16 as our main goal is
- <br>> to get this data on disk.
- <br>>
- <br>> Why are people assuming everything is permanent and bad? I've seen lots
- <br>> of useless demos go on the net and it seemed to me that there might be a
- <br>> few people who might be interested in what it takes to link satellite
- <br>> dishes and major sites such as the U.S. Capitol to the mbone. Believe me,
- <br>> that is not a simple thing to do and, barring the lack of other activities
- <br>> on the net, doesn't seem to be a bad thing to do for a while.
- <br>>
- <br>> You don't have to listen, the streams are not permanent, the ttl is
- <br>> not fixed in stone, and we're learning *lots* by conducting this
- <br>> experiment. Isn't that the purpose of a research environment?
- <br>>
