We are using it because we have developed it.
Biggest problem is we don't have a
good quality unicode font for printing. Presently what we have are good for
web (even with some small problems)
but not for printing.

Sometimes we use pdflatex for preparing e-books.

We have digitised 4-volumes of English Kannada dictionary by using this
package.
Here is the sample for letter Y

http://www.sirinudi.org/Sagar/samples/kandict_y.pdf

Another sample is as follows.

http://www.sirinudi.org/Sagar/samples/anakru.pdf

Nearly 100 schools in Kanakapura district (Karnataka, India) use this
package
to typeset Question Papers and Blue prints. This package is released under
GPL
and available for free download in sarovar.org.

3.) Does Kanlel work only in LaTeX or also in plain TeX?

It works fine in LaTeX. To make it work in TeX we just need to call the
font thats it.
This package does not requires any preprocessing as it is being done in
typesetting
Sanskrit.

I think there is no one-to-one correspondence

So I have to create a file called Kannada.tex which contains hyphenation
patterns
for Kannada and put it in the TDS and start using it. Am I right?

Ok I will try this.
