- Am I totally misunderstanding what you say, or are you just describing
- the function of CRC's ?? The combination a file's length in bytes and
- its 32-bit CRC (cyclic redundancy check) is virtually unique and serves
- to validate many software packages. This, in essence, is no different
- to validating experimental records as original.

- : What is needed to make computerized lab notebooks feasible
- : is a similar service on the internet (maybe BioSci could offer it)
- : where "signature" files could be publically posted and permantly

- What is needed to make data accessible is ISDN!!
-
- The whole thrust of new developments is NOT to cart your precious data
- around the world with you, but to make access to it via wide-bandwidth
- communications channels feasable. What you need is a WORM at work as a
- data repository and an ISDN link on your portable in order to get at it
- from home or wherever you are working.
-
- My hope is that this will all be affordable - otherwise we will have no
- progress. I'm not saying that the 'Newton' or 'Active Book' are the
- answer either. The essence of what I am saying is that the
- communication channel itself is the expensive bottleneck. The
- significance of systems like ISDN is that it is *designed* for digital
- communication not adapted for it.
-
- Many people (myself included) dialup via voice lines with ~2400 baud
- connections to get at their data. This is obviously a severe
- limitation but I have a *vast* array of information available in
- comparison to what I could carry around on a portable. What *I* want
- is an ISDN link so that files on the network are available to me as if
- they were stored locally on the PC at home. This is quite practical
- now (if a little expensive).
