There is a simple low-tech option. Setup a CRON job that does svn
update on a local checkout, tars the result and posts it on a server
in the LAN in India. When developers need to do a checkout they can
download and extract the tar and just run svn update to catch up to
HEAD quickly. They can easily use switch to change to a branch pretty
efficiently. I know a lot of users that use this successfully.

If you use Apache, you can use the WebDAV proxy. This takes your
svnsync idea a step further by making the local server act as a proxy
for the master on write operations. There are several advantages of
this approach over your suggestion.

1) Developers do not need to use switch. They just checkout from
their local mirror and work as normal. The mirror handles proxying
requests back to the master when needed.

2) Since developers do not need to use switch, they can use the mirror
for more than checkout. Commands like log/diff/update/switch/merge
are all processed by their local mirror and give the performance
benefits from this,

This is what the ASF uses for their repository. They have a mirror in
Europe that committers in Europe connect through when working with the
ASF repository.
