- Hi -
-
- I don't share your optimism about `everyone outside the USA using X.400
- in 10, if not 2 years'. The market has clearly picked RFC mail over X.400,
- and that is where the interoperable infrastructure is. The X.400 community
- has cajoled, exhorted, and even threatened in the past 10 years that they are
- going to take over the world, and it hasn't happened yet. Some people have
- said that MIME was the final nail in X.400's coffin; I suspect it will occur
- when a few more PTT's (particularly Deutsche Bundespost) have their fangs
- pulled.
-
- As my boss is fond of pointing out, one must not limit his perspectives
- by the tools available to him. The present absence of suitable chisels
- doesn't mean that it is right to enshine screwdrivers as the tool to chisel.
- A common filesystem certainly does not exist today; but that does not mean
- that it may not exist tommorrow.
-
- More to the point: IMAP's scope *is* likely to expand, but I am not
- convinced that it should expand in areas where it currently has no presence.
- It is one thing to talk about expanding IMAP's distributed information
- retrieval capabilities to objects other than mail; it is quite another for it
- to become a distributed manager of user file or environment objects. In the
- former case, you are expanding the scope of objects under a general category
- and manipulation that currently exists; in the latter, you are creating new
- categories of objects and new forms of object manipulation.
-
- Your point about the delay in IMAP2 support is well-taken, but it
- suggests something totally different to me than it does to you. POP had an
- earlier presence, and it remains substantially simpler than IMAP. Both of
- these are immense benefits. The present interest in IMAP has come about due
- to an understanding of the limitations of the POP model. However, the more
- IMAP `goes off the deep end', the more the simplicity of POP remains the more
- attractive choice.
-
- My source files suggests that the cost of implementing IMAP is about
- twice that of implementing POP; more accurately, my IMAP server source file is
- about twice the length of my POP server (30K vs 15K). That's a price to bear,
- but perhaps not too much given the benefits. We don't want to make that ratio
- worse.
-
- As taxing authorities around the world have discovered, you can get a lot
- more out of people in small increments taken repeatedly over a long period of
- time than in massive whallops delivered at once... ;-)
