If you don't use texfont.pl, the main thing you need to do is to find out 
what the names are of the tfm's that fontinst generates.

You can make typescripts as simple as you want, skipping symbolic names, or 
even not using typescript and using \definefont directly, but then you 
loose a couple of abstractions.

Say that you have this palatino and that you used fontinst to generate ec 
encoded fonts, then you have to make a script like:

\starttypescript [serif] [adobepalatino] [ec]

   \definefontsynonym [Palatino]      [thefontinstgeneratedname]
   \definefontsynonym [PalatinoBold]  [anotherfontinstgeneratedname]

\stoptypescript

It's a serif font, so now we define an accompanying serif script:

\starttypescript [serif] [adobepalatino] [name]

   \definefontsynonym [Serif]      [Palatino]
   \definefontsynonym [SerifBold]  [PalatinoBold]

\stoptypescript

Say that you put these script in a file called typeface.tex that you put 
somewhere where tex can find it. In your document (or style) you now need 
to tell context that you need this file:

\usetypescriptfile[typeface]

you will probably have a map file too and you can either load that one in 
pdftex.cfg or let context do that.

The next thing is using this font. Of course you can execute typescripts 
yourself but best is to use the command

\definetypeface [myface] [rm] [serif] [adobepalatino] [default] [encoding=ec]

this means as much as: create a typeface, map it to the rm families, using 
the serif definitions of adobepalatino matching encodning ec, and use the 
default size definition scripts.

In a similar way you can add ss, tt, mm, etc definitions to this typeface 
'myface'. Bewaqre, use rscale=... to achieve relative scaling, if needed.

Now you need to activate this typeface (because each typeface has its own 
namespace, you can mix 'm any way you want]

\setupbodyfont[myface,10pt,rm]

Now you should have an adobe palatino document.

If you do it this way, you can also say (handy for titlepages and so):

{\definedfont[SerifBold at 60pt]This is a big title}

or

\definefont[VeryBigFont][Palatino at 150pt] \VeryBigFont Guess what 
(happens after \setuphead[chapter][style=VeryBigFont])

Now, the whole idea behind this concept is that you can build your own set 
of definitions (typefaces); here we have for instance one typeface.tex file 
per project and a couple of general system wide ones for ourself.

Back to texfont vs fontinst: in the case of texfont, you can more 
conveniently mix multiple instances, like three regular weights of a 
multipel master, or seven different slanted palatino's; in the case of 
fontinst you have the advantages you already mentioned, but you're on your 
own to figure out what file names are used as well as prevent nameclashes 
yourself].

BTW, does patrick still has this idea of reprogramming those font tools?
